Certificate of Origin for Exporters
When you need a certificate of origin, what it must contain, and how it has to match your commercial invoice.
What it is
A certificate of origin (COO) states where goods were grown, manufactured, or substantially processed. Destination customs uses it to apply the correct tariff treatment — including preferential duty under a free-trade agreement when the form and content meet the scheme rules.
It is separate from the commercial invoice. The invoice bills the goods; the COO certifies origin. Buyers, banks, and customs often require both, and the goods description should agree across them.
Preferential vs non-preferential
Non-preferential (ordinary) certificates prove origin for general customs, quota, or anti-dumping purposes without claiming a tariff preference.
Preferential certificates (or self-declarations under some FTAs) claim reduced or zero duty under a specific trade agreement. Rules of origin, formats, and issuing bodies differ by scheme — confirm which instrument the buyer’s customs authority accepts before you ship.
Required fields
Typically: exporter and consignee details, goods description and quantity, marks and numbers, country of origin, invoice reference, transport details when required, and the authorised signature or stamp of the issuing chamber, agency, or self-certifying exporter.
Under a letter of credit, the COO must also satisfy any LC wording on who issues it, what it certifies, and whether originals or copies are required.
Common mistakes
A goods description that does not match the commercial invoice. Claiming preferential origin without meeting the FTA’s rules of origin. Using the wrong form for the destination market. Leaving the COO until cargo is already at the port.
Another frequent issue: invoice number or date on the COO that does not tie back to the commercial invoice presented to the bank or customs.
How it must match other documents
Origin on the COO should match country-of-origin statements on the commercial invoice. Quantities and descriptions should agree with the invoice and packing list. Consignee details should not conflict with the transport document when both are examined together.
How Bilexor helps
Bilexor keeps shipment, buyer, and goods details on one record so the commercial invoice and packing list stay consistent — the same descriptions you will need when applying for a certificate of origin.

Frequently asked questions
Who issues a certificate of origin?
Often a chamber of commerce or authorised agency; some trade agreements allow approved exporters to self-certify. Requirements depend on the destination and whether preferential treatment is claimed.
Do I need a certificate of origin on every shipment?
Not always. Many destinations request it for customs or FTA claims; LCs and buyer contracts may also require it. Check the buyer’s instructions and the LC before assuming you can skip it.
